I won't criticize it since I don't understand the details. However, I do have some superficial hypothetical opinions regarding the idea.

1, From the short description it seems as if it actually choses to overexpose and takes care of the overexposed pixels via their resetting mechanism.

2, It sounds as a smarter version of Fujifilm EXR mechanism. Similarly as in the case of EXR sensor, one group of the pixels is used for capturing the shadows, the other group is used for capturing the highlights. But in the case of the EXR, membership of a pixel to either group is predetermined (the well known EXR pixel layout), while in case of the Rambus' BinaryPixel technology the membership is decided based on the actual exposure process taking place.

3, Practice has shown that EXR approach works in expanding the DR, but some sensor area is actually wasted. The Rambus technology essentially means you'll get the benefits of EXR without the infamous EXR drop in resolution.

Hugo808: So the advertising department gets to say it's a sharper camera because of the lack of an OLPF, which you wont notice unless you blow your pics up to 6 foot wide.

But no OLPF means you might get moire which ruins your pics permanently (no matter what they say). Are we supposed to be happy about this? I've waited ages to upgrade my D90 but I am not going to risk moire as I shoot a lot of weddings. You can hardly ask the bride to remove her veil because Nikon can't make a decent camera any more.

I think photographers should be put back in charge of camera design at Nikon. Or at least give us a D7100e which has the OLPF put back where it's supposed to be!

The fact is that with resolutions this high the risk of moire is almost negligible.

Macx: More megapixels does not equal less resolution guys and girls. You HAVE to compare the final output. Looking at it on a pixel-per-pixel basis is meaningless in a photography context.

Now, I agree that 20 megapixels behind a comparatively tiny lens aperture sounds like trouble, and it obviously isn't marketed for enthusiasts, but maybe Casio uses the extra data-points for some clever automatic noise reduction and sharpening which is appreciated by the snapshooters this is marketed for.

Or maybe they just want to distinguish it from other P&S in its price range.

Hey, but what about diffraction ? Such a tiny pixels are more sensitive to the effects of diffraction. You can combat the resulting loss of sharpness by using larger apertures, but this thing has also tiny aperture: f/3.5-f-6.5.

BTW, this thing has CCD sensor. It's very well known that CCDs are particularly badly affected by high pixel density.

ilya82: Got mine yestersday. The first thing I can say -for me this camera is a reincarnation of the legendary 5D :) Pictures has the same charm as 5D had.Very happy!

After reading your comment I've got a bit curious and went through DPR sample gallery of 5D. While the samples were certainly great visually, I am astonished how much shadow noise was present in higher ISO images in those days.

brianj: Interesting, it has the same size and type of sensor at the canon SX260HS, yet has not got as wide angle nor anywhere near as much zoom. Ah, I see, its called enthusiast because it sports a f1.8 aperture lens.

I wondered what the name 'enthusiast' meant!

@R. Butler:

pity I can't assign more than one "like" to your reply ! I really wonder why is it so tough for many to grasp the benefit of low ISOs enabled by fast lens.
